Treatment of focal benign lesions of the bone: MRgFUS and RFA

Abstract

The objective of this study was to evaluate the role of MR-guided focused ultrasound surgery and radiofrequency ablation in the management of bone and soft-tissue lesions. Musculoskeletal interventional radiology represents an interesting option for the treatment of benign bone and soft-tissue lesions to avoid the invasiveness of surgery and related risks. The imaging techniques now available, besides representing an optimal guide, allow control of the temperature reached in the region of interest, avoiding or minimizing damage to the sensitive structures surrounding the lesion. INTRODUCTIONInterventional radiology (IR) procedures are well established in the treatment of malignant, particularly metastatic, diseases of bone and soft tissues and are exhaustively described in literature.

CT-guided radiofrequency ablation of spinal osteoblastoma: treatment and long-term follow-up

“…RF thermal ablation is a safe and effective method for the treatment of OO and OB appearing in various localisations [10,14,15]. These tumours may affect the spine, although treatments for spinal OO are more commonly described in the literature than for spinal OB [9].…”

“…Technological developments in recent years have enabled great precision in delivering energy for thermal ablation [14][15][16][17][18][19]. The energy delivered by the needle creates a rise in temperature around the tip.…”

Magnetic resonance-guided focused ultrasound surgery treatment of non-spinal intra-articular osteoblastoma: feasibility, safety, and outcomes in a single-center retrospective analysis

“…MRgFUS is a viable less invasive approach, well-established for definitive or palliative treatment of primitive or secondary bone lesions [10,12,15,21,22].…”

Anaesthetics, steroids and platelet-rich plasma (PRP) in ultrasound-guided musculoskeletal procedures

“…The use of diagnostic imaging techniques such as US, CT and MRI to guide or to verify the effect of musculoskeletal intervention is also widespread (78,79,80,81,82). Infiltrative therapies employed in interventional musculoskeletal radiology are very effective and versatile clinic-therapeutic tools (1,2,4,8,9,25,34,43,56).…”
